    摘要： There is provided a piezoelectric pump including a piezoelectric vibrator formed by stacking a piezoelectric body on at least one of the front and rear surfaces of a shim made of a conductive metal thin plate, and a housing that makes the peripheral edge of the piezoelectric vibrator liquid-tight to form a pump chamber. An alternating current is applied to between the shim of the piezoelectric vibrator, and the piezoelectric body to vibrate the piezoelectric vibrator, thereby generating a pumping action. A cylindrical bent part is formed at a peripheral edge of the shim of the piezoelectric vibrator, and a liquid-tight seal member is interposed between the cylindrical bent part and the housing. As a result, the piezoelectric pump with a highly-reliable fluid-tight structure around the piezoelectric vibrator is obtained.

    摘要： Two piezoelectric ceramics are equal to each other in the polarization directions thereof. Two electrodes disposed on both surfaces of one of the piezoelectric ceramics are connected to an AC voltage source, while other two electrodes disposed on both surfaces of the other piezoelectric ceramic are connected to another AC voltage source having a phase 180° (2π) different from that of the AC voltage source. The two AC voltage sources are biased to a positive voltage side. Accordingly, the invention provides an electro-mechanical transducer capable of greatly increasing the displacement amount of the film thickness of the electromechanical transducer and of preventing the polarization loss of the electro-mechanical transducer.
